I remember I was disappointed in Miracle Day too, but I've thought about watching it again on Netflix to see if time has been a little kinder to it.
Miracle Day is not on netflix, unless you go with the disc option or something.
One thing I was wondering (And maybe this might help when I'm watching it) was if the further we get from when Children of Earth originally aired the more kinder Miracle Day might be. I mean it seems like we're comparing Apples to Oranges here. Children of Earth was so well done and so focused that comparing anything to it would seem a little unfair. Now if we compared Miracle Day to Season 1 or 2, I wonder how it stands up, and that could be exciting.
